The aim of the paper is to validate the use of measurement methods in
the study of GFRP joints. A number of tests were carried out by means of
a tensile machine. The studies were concerned with rivet connection of
composite materials. One performed two series of tests for two different
forces and two fibre orientations. Using Finite Element Method (FEM) and
Digital Image Correlation (DIC), strain maps in the test samples were
defined. The results obtained with both methods were analysed and
compared. The destructive force was analysed and, with the use of a
strain gauge, the clamping force in a plane parallel to the annihilated
sample was estimated. Destruction processes were evaluated and models of
destruction were made for this type of materials taking into account
their connections, such as riveting.
